Also I wish I had bought Costco years ago, though it's not anywhere on that list.
Every year I wonder if it's too late, and don't buy. I've never owned it.

I got into Costco more than 20 years ago before I had even heard of value investing. Because I had small sums to invest and discount brokers charged $15 per trade, I enrolled in free dividend reinvestment. The accumulation and compounding has paid off handsomely. I would probably not have bought any more shares after the initial purchase. Now the decades old DRIP shares look like bargains, though they were probably overvalued by PE measures.

Almost all great successful growth companies spend most of the time near all time highs. Constellation Software, a 100 bagger since IPO has been a 15 bagger over the last 10 years. Presumably it has been overvalued most of the time. It's current PE is 78. PCF is 30 and Free CF growth is projected at 12.6%
